It's too small for any prayer of not smacking into him to have worked, she knows that, and she still freezes a little when suddenly it is happening. Her skin went even more sensitive between the prickle from the air and now doing whatever her nerves were doing because of the sudden deluge of hot water meeting all of the muscles faced with her stonefaced requirement until now.

But she's on a mission that goes in one direction, which means her jaw stiffens, and she still forces herself to sit down rather than jump back. Not that there's even room for that. She's surprised to find Cas' eyes still closed even as he pulls back in the who knows what space, and she can fully settle under the water. Tell herself to breathe (even if it's all weird herbs and something a little sweet she's breathing in from the foam).

She closes her eyes and is about to breathe in again when Cas speaks, and she almost wishes he hadn't as he went right on. But he is, and she opens her eyes to find him looking at her. Asking that question. There's a press of breath out of her nose and the most predictable of words, even if they are said quietly. "I'm fine, Cas—"

Even if her entire body is in the middle of either writing her a strongly worded letter about how that is wrong or just divorcing her from her own bones and giving them to the heat pressing in on all sides. Not to mention. Basically. Everything else.

"—and it's not a waste if the things make you feel better."
No matter what might be on her plate, he was in the worst (second worst?) of all of them.
